Using a lightweight business cases provides just enough structure to ensure good investment decisions based on value without going so far as to define requirements or fix scope. It informs the strategy and investment funding responsibility of the Program Portfolio Management team. Created during the analysis stage in your Portfolio Kanban, the lightweight business case captures:
- Solution alternatives
- Potential paths for incremental implementation
- Determination of costs
- Identification of technology & architectural enablers
- Definition of scope (in and out of scope)
- Non-functional requirements
- Impacts to other products, programs or services
In addition to these items, this lightweight business case will also provide refinement to WSJF prioritization compared to other epics. WSJF is a construct of the Scaled Agile Framework® which is defined as:
Weighted Shortest Job First (WSJF) is a prioritization model used to sequence “jobs” (features, capabilities) so as to produce maximum economic bene t in a ow-based system. WSJF is calculated as the cost of delay divided by job duration (or job size as a proxy).
Based on this information, stakeholders with sufficient content and budgetary authority consider approval of the epics. A lightweight business case and “go” decision from this authority should be considered pull criteria for the Backlog stage of your Portfolio Kanban.
